After word broke Wednesday regarding Alistair Overeem’s failed pre-fight drug test, the rumor mill starting buzzing over who should replace “The Demolition Man” and challenge champion Junior dos Santos for his heavyweight crown at UFC 146. The current front-runner to serve as substitute is Frank Mir (Pictured), who is presently slated to co-headline the show against Cain Velasquez in a top contender shootout.

Although the former title holder has yet to receive an official offer, Mir is fully prepared to if the phone does ring.

“I would be excited if given the opportunity to compete for the UFC’s heavyweight title at UFC 146, if the reports released earlier today regarding Alistair Overeem failing his ‘A’ sample drug test are true,” Mir stated. “I have been fortunate to be able to fight in the UFC for more than a decade and it is a dream of mine to become the first three-time heavyweight champion in the UFC.

“Being able to fight Junior dos Santos would put me one step closer to that dream.”

Mir is perfect through his last three fights. He was last seen snapping Antonio Rodrigo Nogueira’s right arm in two at UFC 140 in December.

The 32-year-old originally captured the UFC heavyweight crown in 2004 before a motorcycle accident forced him to vacate the strap. Mir also won an interim belt in December of 2008 before losing a title unification bout to Brock Lesnar seven months later.
